version 0.35 test 28 by Dave Sabine as part of a project called pddp
proposed by Krzysztof Czaja to build comprehensive documentation for
Pd. Jonathan Wilkes revised the patch to conform to the PDDP template
for Pd version 0.42.;

#X text 19 329 Miller's original example shows how a list of floats
can be delayed by [pipe]. Note that the [trigger] object is used to
ensure that [pipe] receives the messages from right to left order.
;
#X text 18 25 1) If only one creation argument is used \, it defines
the initial length of delay. [pipe] will then expect a float.;
#X text 17 87 2) If two or more arguments are provided \, then all
except for the last will define the data type to be expected at the
corresponding inlet. The delay time is initialized by the LAST creation
argument \, which can be changed by sending a new delay time to the
rightmost inlet.;
#X text 72 240 Messages can be sent as lists like this example.;

#X text 169 93 The [pipe] object stores a sequence of messages and
outputs them after a specified delay time in milliseconds. You can
change the delay time as you wish. The outputs are sorted automatically.

;
#X text 168 373 - the rightmost inlet takes a float value that specifies
the length of the delay (in milliseconds).;
#X text 168 327 - an additional inlet is created for each argument
provided to [pipe] besides the delay time. This makes it possible to
send lists through [pipe].;

#X text 168 409 - pipe can output symbols \, floats \, pointers. One
outlet is created for each argument provided (besides the final argument
to specify delay time).;
#X text 167 475 - (optional) creation arguments define the data type
to be expected at each inlet: "f" for float (or a float \, like "41"
\, to initialize the value) \, "s" for symbol \, and "p" for pointer.
The final argument defines the initial length of delay. See the subpatch
below for more about the arguments:;
